Most metals are oxidized by heat, oxygen, salt, humidity and chemicals over time, and these chemical reactions change unique properties, shape and color. Bubble Monster 'Metal', which has strong heat resistance against high temperatures, is a special solution designed for metals, especially automobile wheels & calipers operating in the worst environment. It not only protects metals from oxidation and corrosion, but also prevents surface damage due to debris with a hardness of 9H, significantly slowing the progression of gradual breakage and maintaining the original color and gloss.
